V ROTARY sNowPLow;

Application filed January 30, 1925. Serial No. 5,743.

To all whom it may concern:

Be it known that I, HENRY C. F. HAAGE, a citizen of the United States, and'resid'ent of Akron, county of Plymouth, State of Iowa, have invented a new and useful Rotary Snowplow, of which the following is a specification. i

p The object of this invention is to provide a simple and economical means for removing snow from streets, highways and the like.

More specifically theobjectof this invention is to provide a snow plow which may be secured to or removed from a tractor in a very few moments.

A further obj ect is to provide a snow plow which will deposit the snow at the side of the road or in a truck. A

A further object is to provide a snow plow which may be lowered or elevated while in use. I i

' These and other objects will be apparent to those skilled in the art.

' 'My invention consists in the construction,

arrangement and combination of the various parts of the device, whereby the objects contemplated are attained as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in

which Fig.1 is aside elevation of my complete device installed on a tractor with portions of the tractor cut away to more fullyillustrate the means employed to secure the shovel to the tractor. r

Fig. 2 is a plan view of my snow shovel ready for installation on a tractor.

Fig. 3 is a sectional view of the power take off, taken on line 33 of Fig. 1; i

F ig. 4 is a sectional view of the hanger means employed to secure the shovel to the front axle of the tractor and is taken on line 44 of Fig. 1.

I have designated the ordinary tractor-by the'numeral 10. The numeral 11 designates the frame of my snow plow and is of V design. This frame is designed to be secured at 12 and 13 to the axle 14 of the tractor 10 by the hangers 15. Secured to the rear end of the tractor and positioned above the rear end of the frame 11 is the bracket 16. Threaded into this bracket is the screw 17 which frictionally engages. the well 18 in the end of the frame 11. Mounted on the front of this frame is the shovel 19. The numeral 20 designates an upturned flange ar und the side and back of the shovel to preventthe snow from falling over the sides and back of the shovel. Secured to the front of the shovel are the runners 21, which are designed tosupport the shovel a certain distance from the ground. Near the rear of the shovel 19 is the opening 22 which communicates with a blower box designated by the numeral 23. The numeral 24 designates a centrifugal fan mounted. in the blower box 23. The numerals 25 and 26 designate pipes which communicate with the blower box and are so positioned relative to the force of the fan 24 that the snow entering the blower box is blown through them.

At each of their outlet ends is a deflector or. I

bafile plate, which I have designated by the numerals 27 and 27. They are pivotally mounted so'that they may be adjusted to various positions. These positions may be permanently. retained by tightening the 7,

thumb screws 28 and 28. The numeral: 29 designates a brace that is secured to the frame and the pipes 25' and '26. Securely attached to the fan shaft 30 is the bevel gear 31', which is shown in Fig. 2. The numeral 32 designatesa shaft journaled in the bearing 33. Atone end it has permanently secured thereto the bevel gear 34 which engages the first mentioned bevel gear 31... Se cured to the'other end of the shaft 32 is, another bevelgear which is designatedby the numeral 35 which engages the bevel gear 36 secured to the second shaft 37. This shaft 37 is journaled in the housing 38 which is designed to be b'oltedto the tractor and'over the power take off by the studs 39 and 40. Secured to this shaft and within the housing 38 is the bevel gear 41 which engages the bevel gear .42. This bevel gear 42 is mount ed on-thepower shaft of the tractor lO. I

have designated this shaft by the numeral 43 and the bearing the numeral 45. p I r The practical operation ofthis invention is as f0 lows:

Place the complete device beneath a tractor. Secure the hangers 15 to the axle 12 and screw the member 17 down until it engages the well 18 in the frame 11. Connect the fan driving mechanism to the power take off and the shovel is ready for use. It will readily be noted that if the member 17 is screwed up or down the front end of the in h h it s i i ele by shovel will be lowered or elevated, the necessity of which will be readily understood. As the fan mechanism is in engagement with the power take off of the tractor the fan will be in operation as soon as the motor is started. As the tractor moves forward the snow is forced upon the shovel 19 and as there is a suction at the opening 22 the snow will be drawn through this opening into the blower box and from here will be forced through the pipes 25 and 26 and deposited at the side of the road. The position of depositing this snow along the road may be regulated by the deflector plates 27 and 27. If it is desired the pipes 25 and 26 may be elevated to such a position that the snow may be deposited into a truck. To remove my attachment from the tractor, merely detach the fan driving mechanism from the power take off and detach the hangers 15 from the front axle.

I-Iaving fully described my invention, what I claim and desire to obtain by Letters Patent, is:

'1. In a device of the class described, a snow shovel having an opening, a blower box below said opening and communicating with said opening, flanges on the sides of said shovel converging rearwardlyso that the snow is directed into said opening, a centrifugal fan mounted within said blower box, means for rotating said fan, and outlet pipes communicating with said blower box, for the purposes'stated.

2. In a device of the class described, a snow shovel having an opening, a blower box below said opening and communicating with said opening, flanges on the sides of said shovel converging rearwardly so that the snow is directed into said opening, a centrifugal fan mounted within said box, pipes leading from said box, deflector plates at the ends of said pipes, and means for rotating said fan, for the purposes stated.

3. In. combination with a tractor having a power take off, a rotary snow plow, comprising a shovel having an opening, a blower 30x communicating with said opening, flanges on the sides of said shovel converging rearwardly so that the snow is directed into said opening, a centrifugal fan mounted within said box, a pipe leading from said box, and means for operatively connecting the power take off ofsaid tractor to rotate said fan, for the purposes stated.

4. In combination with a tractor, a rotary snow plow, comprising a shovel having an opening, a blower box communicating with said opening, flanges on the sides of said shovel converging rearwardly so that the snow is directed into said opening, a centrifugal fan mounted Within said box, pipes leading from said box, adjustable deflector plates at the end of said pipes, and means for rotating said fan by the engine of said tractor.
